Answer: A
Explanation:
The buoyancy force only takes affect when an object is placed in water and floats. This occurs because the density of that object is less than the density of water.
Water is the main liquid used for measuring the density of an object.
Hope this helps! Please tell me if I am wrong :3
Answer:
1290 atm
Explanation:
P1V1=P2V2
P2= (P1V1)/V2
P2=(2.15 atm * 750 mL)/(1.25 mL)
P2=1290 atm
Answer:the answer is B.) H2O3(aq) and Mg (OH)2(s)
Explanation:
The answer should be B, it reacts in air to form a green layer.
Chemical properties means that how the substance that reacts with other substance to produce new substances. Usually it cannot be measured or observed just with the substance itself.
From all the options above, only B is a reaction. The green layer formed is a new substance produced by copper and air. It involves a chemical change.
Other options like boiling points or state of matter, these are physical properties. They do not require it to react to other substances and the can be measured and observed easily.
